oracle调用shell

1，创建java source
create or replace and compile java source named Execshellcmd as
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;

public class Execshellcmd {
  public static String callShell(String path) {
    String message = "";

   try {
      Process process = Runtime.getRuntime().exec(path);
      int waitFor = process.waitFor();

      InputStream is = process.getErrorStream();
      InputStreamReader isr = new InputStreamReader(is);
      BufferedReader br = new BufferedReader(isr);
      String line = null;
      while ((line = br.readLine()) != null) {
        message += line;
      }

      message += " Process waitFor=" + waitFor;
      int exitValue = process.exitValue();
      message += " Process exitValue=" + exitValue;
    } catch (Exception e) {
      message = e.getMessage();
      e.printStackTrace();
    }

    return message;
  }

}

2, 创建存储过程或者函数进行调用
create or replace function fun_callshell(p_command   STRING) return varchar2
AS LANGUAGE JAVA
NAME'Execshellcmd.callShell (java.lang.String) return java.lang.String';

create or replace procedure pro_callshell(p_command   STRING)
IS LANGUAGE JAVA
NAME'Execshellcmd.callShell (java.lang.String)';

3，赋权
begin
dbms_java.grant_permission('LOGE','SYS:java.io.FilePermission','<>','read,write,execute,delete');
end;
begin
dbms_java.grant_permission('LOGE','java.lang.RuntimePermission','*','writeFileDescriptor' );
end;

4，测试
select fun_callshell('/home/oracle/1.sh') from dual;

第二种 使用scheduler
测试sys用户执行，
begin
  DBMS_SCHEDULER.create_job (job_name => 'test', job_type => 'EXECUTABLE', job_action => '/home/oracle/1.sh');  
end;
或者带有执行间隔的：
dbms_scheduler.create_job(job_name=>'j_test',job_type=>'executable',job_action=>'/home/oracle/1.sh',start_date=>sysdate,repeat_interval=>'freq=daily;interval=1',number_of_arguments=>1);

执行：
begin
  DBMS_SCHEDULER.run_job (job_name => 'test');  
end;
